Place it as a square. Vision type 10. Why would you even try to inspect leads on this? It's not like they could get bent.

Hi, Thats the way I have been placing it but we have seen a few misplacements failing in test and I am trying to improve the placement accuracy and consistency by locating the leads/pads . aj

We have a PVA conformal coating machine that is working good for us. you might also want to give them a try. just my 2 cents worth...not associated with PVA in any way

All, I am trying to assertain if our Dross Formation on the Wave Solder Machine is in line with others. I estimate that we generate about 30 kgs/monthly in a 550kg bath. Any replies appreciated. aj

This is common with older Fujis. The machine is trying to download production data to the host(MCS?) If the cable is not connected or if the MCS is off, the machine will randomly freeze at the end of prod. Either solve those issues or change the m

It's probably too late now, but try searching the fine SMTnet archives. Trust me, there have been LOTS of discussions about stencil washers here.

Years ago we hired a consultant who helped try to resolve our high solder defect rates. He recommended the use of finger cots - $50,000 in consulting fees later, we still had the same defects.

Hello Dougs: Have you tried stenciling solder paste to the BGA part itself. You will find this most helpful for your heat transfer and attachment integrity of the component in a Pb free process.

Dougs, Make sure they use the same solder that you plan to use. In my case they were unable to get acceptable solder joints with our solder. We use no-clean P1 flux in our cored solder. So I recommend you try before you buy. Jerry

I had something similar a while back it looked like fibreglass insulation in my case (was using no clean flux not water based), i took some and melted it with a soldering iron and it reacted like flux. and i tried disolving it with acetone.
